# OpenClaw / Clawhip Routing Contract
|
|
|
|
This document defines the normalized event contract OMC emits through the OpenClaw bridge for native Clawhip-style consumers.
|
|
|
|
## Goals
|
|
|
|
- Keep the raw hook event (`event`) for backward compatibility.
|
|
- Add a normalized `signal` object for routing and dedupe-friendly filtering.
|
|
- Make command/native gateways receive the same logical payload shape as HTTP gateways.
|
|
|
|
## Payload shape
|
|
|
|
HTTP gateways receive JSON with this structure:
|
|
|
|
```json
|
|
{
|
|
"event": "post-tool-use",
|
|
"instruction": "...",
|
|
"timestamp": "2026-03-09T00:00:00.000Z",
|
|
"sessionId": "...",
|
|
"projectPath": "...",
|
|
"projectName": "...",
|
|
"tmuxSession": "...",
|
|
"tmuxTail": "...",
|
|
"signal": {
|
|
"kind": "test",
|
|
"name": "test-run",
|
|
"phase": "failed",
|
|
"routeKey": "test.failed",
|
|
"priority": "high",
|
|
"toolName": "Bash",
|
|
"command": "pnpm test",
|
|
"testRunner": "package-test",
|
|
"summary": "FAIL src/example.test.ts | ..."
|
|
},
|
|
"context": {
|
|
"sessionId": "...",
|
|
"projectPath": "...",
|
|
"toolName": "Bash"
|
|
}
|
|
}
|
|
```
|
|
|
|
## `signal` contract
|
|
|
|
| Field | Meaning |
|
|
| ---------- | --------------------------------------------------------------------------------- |
|
|
| `kind` | Routing family: `session`, `tool`, `test`, `pull-request`, `question`, `keyword` |
|
|
| `name` | Stable logical signal name |
|
|
| `phase` | Lifecycle phase: `started`, `finished`, `failed`, `idle`, `detected`, `requested` |
|
|
| `routeKey` | Canonical routing key for downstream consumers |
|
|
| `priority` | `high` for operational signals, `low` for generic tool noise |
|
|
|
|
Additional fields may appear when applicable:
|
|
|
|
- `toolName`
|
|
- `command`
|
|
- `testRunner`
|
|
- `prUrl`
|
|
- `summary`
|
|
|
|
## Native command gateway contract
|
|
|
|
Command gateways now get the same normalized payload through both:
|
|
|
|
- template variable: `{{payloadJson}}`
|
|
- env var: `OPENCLAW_PAYLOAD_JSON`
|
|
|
|
They also receive convenience env vars:
|
|
|
|
- `OPENCLAW_SIGNAL_ROUTE_KEY`
|
|
- `OPENCLAW_SIGNAL_PHASE`
|
|
- `OPENCLAW_SIGNAL_KIND`
|
|
|
|
That lets native Clawhip routing consume one contract whether the transport is HTTP or shell-command based.
|
|
|
|
## Current high-priority route keys
|
|
|
|
- `session.started`
|
|
- `session.finished`
|
|
- `session.idle`
|
|
- `question.requested`
|
|
- `test.started`
|
|
- `test.finished`
|
|
- `test.failed`
|
|
- `pull-request.started`
|
|
- `pull-request.created`
|
|
- `pull-request.failed`
|
|
- `tool.failed`
|
|
|
|
Generic `tool.started` / `tool.finished` remain available as low-priority fallback signals.
|
|
|
|
## Noise reduction
|
|
|
|
- `AskUserQuestion` now emits only the dedicated `question.requested` signal instead of also emitting generic tool lifecycle events.
|
|
- OpenClaw now collapses repeated attached-tmux lifecycle bursts before dispatching them to downstream native gateways.
|
|
- `session-start` collapses on `{projectPath, tmuxSession}` for a short burst window.
|
|
- `keyword-detector` (the `UserPromptSubmit` bridge surface) collapses prompt-submitted bursts on `{projectPath, tmuxSession, normalized prompt}`.
|
|
- `stop` / `session-end` collapse on `{projectPath, tmuxSession}` for a short burst window.
|
|
- Consumers should prefer `signal.priority === "high"` or explicit `signal.routeKey` filters instead of routing directly on raw hook names.
|
|
|
|
## Stability notes
|
|
|
|
- Raw `event` names are preserved for backward compatibility.
|
|
- `signal` is the preferred routing surface for new native Clawhip integrations.
|
|
- `context` remains a whitelisted subset; internal raw tool input/output are used only to derive normalized signals and are not forwarded in `payload.context`.
